Diksha - you posted many problems here without showing a line of original work. It is time for you to show what you know.
\(\displaystyle\(\displaystyle \mbox{Let }\, \alpha\, \in\, \mathbb{Z}\, \land\, n\, \mbox{ positive integer.}\)
\(\displaystyle \mbox{If }\,\alpha\, \simeq_{prim}\, n\, :\, n\, =\, \Pi_{k=1}^r\, P_n^{lx}\, \mbox{ then}\)
\(\displaystyle \alpha^{-1}\, -\, \alpha^{l(n)-1}\, \mbox{ mod }\,n\)
\(\displaystyle \mbox{with}\)
\(\displaystyle l(n)\, =\, n\, \Pi_{n=1}^{\gamma}\, \left(1\, -\, \dfrac{1}{P_n}\right)
\(\displaystyle \mbox{thus}\)
\(\displaystyle \alpha^{-1}\, \cdot\, \alpha\, \equiv\, 1\, \mbox{ mod }\,n\)\)
